  • a flow control mechanism actuated the lever assembly to move the lever to move the spoon to control the fluid flow through the opening, and the flow control opening includes a plate and a threaded fastener received in an aperture in the plate.
  • a bottom of the threaded fastener is substantially cone shaped and engages the lever at a location of engagement, and as the threaded fastener is turned in one direction, a diameter of the bottom of the threaded portion at the location of engagement increases to move the spoon from the first position to the second position, and as the threaded fastener is turned in an opposition direction, the diameter of the bottom of the threaded portion at the location of engagement decreases to move the spoon from the second position to the first position.
  • a valve assembly in another exemplary embodiment, includes a base structure, a plurality of valves, and a valve mounting assembly that is located between the plurality of valves and the base structure.
  • the valve mounting system includes an upper plate including an upper inlet, an upper outlet, and an upper exhaust, a lower plate including a lower inlet, a lower outlet, and a lower exhaust that are aligned with the upper inlet, the upper outlet, and the upper exhaust, respectively to define an inlet, an outlet and an exhaust, respectively, and a spoon that moves about an axis to control a flow of fluid through an opening.

  • FIG. 7 illustrates a cross sectional side view of the mounting assembly.
  • FIG. 1 illustrates a valve assembly 10 including a plurality of valves 12 mounted on a base structure 14 .
  • a mounting assembly 16 is located between the plurality of valves 12 and the base structure 14 .
  • a cartridge 18 is located in each of the valves 12 to control a flow of a fluid through the valves 12 .
  • the fluid is air.
  • a solenoid 20 and a magnet 22 are located on the valve 12 to control movement of the cartridge 18 to control the flow of fluid through the valve 12 .
  • valves 12 can be mounted in either direction on the mounting assembly 16 (that is, reversed 180°). In one orientation as described below, fluid through an inlet 24 is controlled. If the mounting assembly 16 is mounted reversed, the working fluid through the outlet 26 or through the exhaust 28 can be controlled. This provides better access for the worker. That is, although an inlet 24 is described below, the flow of fluid through the outlet 26 or the exhaust 28 can be controlled.
  • the mounting assembly 16 includes an upper plate 16 a and a lower plate 16 b each including aligned inlets 24 a and 24 b , aligned outlets 26 a and 26 b , and aligned exhausts 28 a and 28 b that define an inlet 24 , and outlet 26 and an exhaust 28 , respectively (shown in FIG. 7 ).
  • the fluid enters the valve 12 through the inlet 24 and is directed to a workpiece (not shown) through the outlet 26 .
  • the valve 12 is not in a working condition, the fluid flows through the inlet 24 and to the exhaust 28 .
  • seals 32 are located around the inlets 24 a and 24 b , the outlets 26 a and 26 b , and the exhausts 28 a and 28 b .
  • the upper plate 16 a and lower plate 16 b are connected by a variety of fasteners 34 and seals 36 to prevent leakage.
  • Each valve 12 includes a spoon 38 that moves about an axis 40 to control flow of the fluid through the inlet 24 .
  • the spoon 38 When the spoon 38 is positioned away from the inlet 24 , the fluid flows freely through the inlet 24 .
  • the spoon 38 can block or reduce the flow of the fluid.
  • the fluid flow When the spoon 38 is in a first position and located away from the inlet 24 , the fluid flow is unrestricted through the inlet 24 .
  • the spoon 38 is in a second position located near the inlet 24 , the fluid flow is restricted or blocked by the spoon 38 .
  • the spoon 38 can be located in any position between the first position and the second position to partially restrict the fluid flow through the inlet 24 , and an amount of restriction of the fluid flow through the inlet 24 increases as the spoon 38 moves from the first position to the second position.
  • the spoon 38 is located between the upper plate 16 a and the lower plate 16 b .
  • the spoon 38 includes a fastening component 42 with an aperture 44 and a covering portion 46 .
  • a lever assembly 30 moves the spoon 38 .
  • the lever assembly 30 includes a wedge or pie shaped lever 48 and a post 50 that extends through the lever 48 .
  • the post 50 extends through the aperture 44 of the fastening component 42 of the spoon 38 .
  • a ball 52 is secured in a portion of the lever 48 .
  • a resilient member 56 such as a spring, is located between the ball 52 and a second ball 54 to bias the spoon 38 to the first position.
  • a flow control mechanism 58 moves the spoon 38 to control the flow of the fluid through the inlet 24 .
  • the flow control mechanism 58 includes a plate 60 including an aperture 62 , and a threaded fastener 64 is received in the aperture 62 .
  • an upper end of the threaded fastener 64 includes a square shaped nut 66
  • a lower end of the threaded fastener 64 includes a cone shaped feature 70 .
  • the threaded fastener 64 is received in an internally threaded nut 68 that secures the threaded fastener 64 to the plate 60 and reduces vibrations.
  • a special tool (not shown) is used to engage the square shaped nut 66 and move the threaded fastener 64 and therefore the lever 48 and the spoon 38 and control the flow of fluid through the inlet 24 .
  • the covering portion 46 is positioned away from the inlet 24 .
  • the square shaped nut 66 is moved by the special tool to move the threaded fastener 64 with the cone shaped feature 70 downwardly to engage the lever 48 to cause the lever 48 to rotate about the axis 40 .
  • the threaded fastener 64 is turned in one direction and moves downwardly, the cone shaped feature 70 also moves downwardly, and the increase in diameter of the cone shaped feature 70 at a location of engagement with the lever 48 causes the lever 48 to move from the first position to the second position.
  • the resilient member 56 compresses between the balls 52 and 54 , and the covering portion 46 of the spoon 38 pivots to the second position to cover a portion or all of the inlet 24 . That is, as the square shaped nut 66 is rotated, the spoon 38 rotates about the axis 40 to the second position to reduce the fluid flow.
  • the covering portion 46 is positioned to cover a portion or all of the inlet 24 .
  • the square shaped nut 66 is moved by the special tool to move the threaded fastener 64 with the cone shaped feature 70 upwardly to engage the lever 48 to cause the lever 48 to rotate about the axis 40 .
  • the threaded fastener 64 is turned in an opposing direction and moves upwardly, the cone shaped feature 70 also moves upwardly, and the decrease in diameter of the cone shaped feature 70 at a location of engagement with the lever 48 causes the lever 48 to move from the second position to the first position.
  • the resilient member 56 expands between the balls 52 and 54 , and the covering portion 46 of the spoon 38 pivots to the first position away from the inlet 24 . That is, as the square shaped nut 66 is rotated, the spoon 38 rotates about the axis 40 to the first position to increase the fluid flow.
  • the mounting assembly 16 allows for a high precision adjustment of the fluid flow.
  • the mounting assembly 16 also allows for a higher airflow than the prior art which employs check valves.
